Akbayan Senator Risa Hontiveros on Friday opposed House Speaker Pantaleon Alvarez's push for a Senate-less constituent assembly calling it a tyrannical process that will establish a "pweradalism."

Hontiveros also expressed her contempt on Alvarez's warning that provinces which would not support the President's move to federalism would receive zero budget.

"This is a clear vulgar abuse of power. They say that change is for the good of the public, but they deprive the very participation of the public if it does not agree with them," Hontiveros said.

Alvarez on Friday threatened those provinces who would oppose the administration's move to federalism with zero bugets, going on record saying Siyempre, yung ibang probinsya ayaw makisama, o di zero sa budget." Earlier Alverez also said that Congress would push through with plans of a constitutional assembly despite the unanimous objection of the Senate.
